Dishwasher Spray Arm Not Spinning

Why a Spray Arm Won't Spin

A spray arm that sits motionless during the wash cycle leaves entire sections of a load untouched by water, regardless of how clean the water itself is. A cracked or worn spray arm bearing, the small plastic ring the arm rotates on, is the most frequent cause, since it wears down from years of water pressure and grit passing through it. A dish, utensil, or pan handle blocking the arm's rotation path is a simple mechanical obstruction that stops the arm cold even when every other component works. Mineral buildup or food debris packed into the arm's pivot point can seize it in place over time, especially in homes with hard water. Low water pressure from a failing wash pump can leave the arm barely turning rather than fully stopped, which looks similar but points to a different repair.

How San Marcos Appliance Repair Fixes It

A technician checks the spray arm bearing for wear, clears any obstruction in the rotation path, removes mineral or food buildup from the pivot point, and tests wash pump pressure to rule out a secondary cause. San Marcos Appliance Repair carries common parts for Whirlpool, GE, Bosch, KitchenAid, Samsung, LG, and Kenmore dishwashers, so most spray arm repairs finish in a single visit. Every completed repair includes a 90-day parts-and-labor warranty, with same-day appointments available seven days a week across San Marcos and North San Diego County.
